The present invention relates to improvements machines of the kind set.

forth in my reviews patent No.. 805281, in which the devices consist of'a fixed pad and a movable ad actuated by aspringcasing carried on a fiide, theupperend'of the latter pad being pressed against the root of the teat, and subsequentl during the further forward movement oft e slide executes a swingingmovement, the lower part .of the pad being pressed against the iteat'while the spr' irlilg-casing above is squeezed together.

1 8 rangement whereby the milking devices may be brought nearer or further from each other in such a manner that they may be adjusted according to the distance between the tests in the longitudinal direction of the cow, without the distance'between the milking-devices fixed and movable pads which are previ-- ously adjusted to the diameter of the teats,

being changed this ad'ustment, that is to say: the fixed and mova 1e .pads move to ether during 't-he adjustment. -The rear king device is stationary on the frame, while the front milking devices are movable.

A form of construction of the milking-ma-.

chine according to the present invention is shown in the accompanying: drawings, in

Figure 1 is 'aplanview of themachine. V, Fig. 2 is a side viewwith some of the parts 5:

removed, among those are all the connectingrods. Fig. 3 shows a partial section-of the- 0 rating mechanism of the rear portion of ti: device. Fig. 1 shows the opersting mechanism of one of the front devices with the part of the adiusting mechwf anisni, partly in section likewise.

present invention consists in the ar-.

rear milking device B, operating the rear of teats of the cow, two front de The machine consists of a fixed frame :A, a

Eachmilking device conslstsoi a fixed pad a and a movable pad b which latter is at the top in'bonnection with the spring-1,38 8 andat the bottom with an upright dguided by l The upright 11 of the movable .pad .on the rear milking device B issituated on a. slide 0 (Fig.3)which is guided in slots in the bottom .ofthe frame A. The upright isiby means of a rod f connected with another.up right g. situated on a slide it andlikewise guided in slots. ;A connecting-rod t is movably attached tothe upright g-by meansof a forked rod, while the otherendofthe .eonnecting-rod is 1 movably connected with crank Z situated on the middle of the drivingshaft It. By rotating the drivingsha;ft. I: supported by hearings in the ame, a backward and forward motion in relation to the fixgdbpad a will be impartedto the-movable pa 4 The two front milking devices Cand E are similarly constructed and arranged sym- ,-metrically round the machines longitudinal The fixedpads a form the rear side of frames m (Fig. 4), the sides of which are provided with turned down flanges net .the bottom (Fig. 2) which .are guided in slots in the machine frame A. The frames m are at the rear in firm connection with .a.hollo'w linder 0 having on the outside as'crew-' read the nut of which is formed by another thread, this latter cylinder is rotatable but j is prevented from moving-in a longitudinal direction by its bearing-g which fixed connection with the machines frame A. The cylinder 1) is connected with or is pro vided with a bevel wheel 'r'into which engage 'two other'bevel' wheels 8 and! (Figs; 1 and 2). The outside wheel is fixed on a-shaft it with hearing in the side of-the frame A, While the interior wheel 1. is fixed on a shaft 12 having its bearings the middle'of the frame A, the other end of shaft 27 is provided with a bevel wheel a; which engages with another wheel 1* which together with the first mentioned, Wheel 7' is fixed symmetrically round the longitudinal axis of the machine.- When nowthe two screws 0 have o posite cut screw-threads for example, as s own in, the drawing Fig. 1, in which the lower screw is a right-handed screw and the upper a left handed screw and having the same pitch, by turning the shaft u the fixed pads a; on the front milking devices will be moved equal distances backwards or for wards.

The uprights d, of the movable padsb on the front milking devices which are likewise guided by slides in slots, are each at the bottom rovided with a rotatable rod y (Fig. 4) w ich in the foremost end is provided with a screw-thread and passes through the hollow cylinders 0 and The threaded part of the rod y,'the threads of which work in opposite direction ofv the threads on the screw- 0 through the cavity of which the rod y is passed andwhich has the same pitch as these, has its nut z in an upright 1. To the cylinder 29 is fastened amounting 2, which with the projection 3 catches in a longitudinal groove 4 in the screw y thereby causing the screwy to revolve with the cylinder 19.,

, When the shaft u is turned, the fixed pads a will, as already stated, be moved backwards and forwards, and through the construction just described, the movable pads will at the same time be moved backwards and forwards likewise, and the screws 0 and y having the same pitch, the pads b will just be carried the same distance backwards and forwards as are the pads a.

By turning the shaft u it is therefore possible to move the front milking devices C and C backwards or forwards in relation to the milking device B until the distance between them is equal to the distance between the cowsforemost and hindmost pair of'teats, and during this adjustment the distance between the fixed and movable pads in the same milking device, does not change. 1

The uprights 1, which at the top form the nuts 2 for the screws 1 are situated on slides 5 (Figpfl) which are guided in slots in the frameA. The slides 5 are at the rear provided with bearings 6 supporting movable connecting-rods 7, the other ends of which are in movable connection with cranks 8 which like the crank Z intended for the rear milking device, are placed on the driving shaft 7c. The two cranks S are spaced diametrically opposite to the crank Z on the shaft. When, therefore, the driving shaft 76 is turned themovable pads of the rear and front milking devices will, alternately, be

- carried backwards and forwards in relation to the fixed pads.

- I declare that what I claim is 1 1. In a milking machine, a frame, a plurality of milking devices mounted on said frame, means for adjusting the relative positions of the front and rear milking devices, said means comprising a screw threaded member connected'to each of the front milk-- her connected to each of the front milking devices, an internally screw threaded member engaging each of the first mentioned members, abevel gear rigidly connected to each of said internally threaded members, gearing engaging with said bevel gears, and

an operating device for actuating said gearing substantially as described;

3. In a milking machine, aframe, hulking devices adjustable on said frame, each of said devices comprising a movable pad, rotary means for adjusting the positions of l milking devices, screw threaded members connected so asto move axially with said movable pads and to rotate with said rotary adjusting means, and operating means for causing the reciprocation of said movable pads, said means comprising screw threadedparts engaging the previously n'ientioned screw threaded members substantially as described.

In witness whereof, I have hereunto signed my name this 22nd day of April 1907, in the presence of two subscribing witnesses.
